Taeko, enter from stage right.
Literal
Taeko [topic-は] stage-right [from-から] enter [imperative-して].
上手 (かみて) means 'stage right' (the audience's left) — a theater term. 登場して is a casual imperative (て-form as command). This is a stage direction, probably from a drama club or rehearsal. The theater-specific vocabulary makes this a niche but genuine learning opportunity.
